What wellboriginal said.
The American Eagle ticket counter (I'm assuming that's who you're on based on the departure time) opens at 5:00, so you'd be waiting fifteen minutes for them to get there if you got there a full two hours early. You would probably make it through security almost every time if you get there less than 45 minutes prior, but is the lost time, hassle, and potentially huge change fee worth it? However, what others said about bag check in is right on, and it's a pretty strict. Also, keep in mind, that 30 minute time is the time for having checked in, not for arriving at the airport. TSA is slow but actually better than they used to be. There are one or two officers that slow the checkpoint to a crawl, but most of the rest of them are fairly reasonable. It's a pretty easy, laid back airport as long as you don't go into it with the mentality of "but this is College Station." I hear those people get left behind all the time.
